SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 275,668, dated April 10, 1883..

Application iled January 3D, 1883. (Noinodel.)

specification, and in which- Figure 1 is a top View of a portion of my improved spring bed-bottom. Fig.l2 is an end view, and Fig. 3 a detailed view, of the same.

ISimilar letters of reference indicate corresponding parts in all the figures.

My invention has relation to spring bed-bottoms; and it consists in the improved construction and combination of parts of the same, as hereinafter more fullydescribed and claimed.

In the accompanying drawings, the letter A represents the springs, and B the slats in the.

b`d. The springs are helical and connected in pairs by the wire forming the spring, passing in acurve from the top ot' one spring to the top of the other. the slats by their lower ends being bent under the slats and driven up in the under side of the same. A wire-cloth covering, G, is placed over all the springs, and fastened at the ends of the bed to the slats by means of three or more The springs are fastened-to v hooks, D, engaging holes E in the slats. These hooks are fastened to the ends ot' the lozengeshaped meshes, which are twisted up to form eyes F, while the other eyes, Gr, which are not provided with hooks, are bent under the upper round ot' the end springs, so as to hold them in place and prevent them from being bent out beyond the edge of the wire-netting.

By this construction great even ness of elasticity is obtained, as the wire-netting will communicate the pressure from one spring to the surrounding ones, and by the springs being held in placey by the turned edges ot the netting therecan bc no displacementot'the springs.

Having thus described my invention', Iclaim and desire to secure by Letters Patent of the United States- The spring bed-bottom consisting ot' the double helical springs A, slats B, having holes E, wire-netting C, having eyes F for the reception of hooks D, and inward-bent eyes G and hooks D, all constructed and combined to operatesubstantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto atiXed my signature in presence ot' two witnesses.
